Driving your vehicle
The Autonomous Emergency Braking (AEB) system is designed to detect
and monitor the vehicle ahead or
detect a pedestrian (if equipped) in the
roadway through radar signals and
camera recognition to warn the driverthat a collision is imminent, and if nec-
essary, apply emergency braking.System setting and activation

Take the following precautions
when using the Autonomous
Emergency Braking (AEB):
This system is only a supple- mental system and it is not
intended to, nor does it
replace the need for extremecare and attention of the driv-
er. The sensing range and
objects detectable by the sen-
sors are limited. Pay attention
to the road conditions at alltimes.
NEVER drive too fast in accor-
dance with the road condi-tions or while cornering.
Always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. AEB does not stop the
vehicle completely and is not
a collision avoidance system.

5-48The warning light illumi-
nates on the LCD display,
when you cancel the AEB
system. The driver can
monitor the AEB ON/OFF status on
the LCD display. If the warning lightremains ON when the AEB is acti-
vated, we recommend you to have
the system checked by an authorized
HYUNDAI dealer.
The driver can select the initial warn-
ing activation time on the LCD display. Go to the 'User Settings Driving
Assist Forward Collision Warning
Late/Normal/Early'.
The options for the initial Forward
Collision Warning includes the fol-
lowing:
Early: When this condition is selected,
the initial Forward Collision
Warning is activated earlier than
normal. This setting maximizes the
amount of distance between the
vehicle or pedestrian ahead before
the initial warning occurs. Normal:
When this condition is selected,the initial Forward Collision
Warning is activated normally. This
setting allows for a nominal
amount of distance between the
vehicle or pedestrian ahead before
the initial warning occurs.
Late: When this condition is selected,the initial Forward Collision
Warning is activated later than nor-
mal. This setting reduces the
amount of distance between the
vehicle or pedestrian ahead before
the initial warning occurs.

Prerequisite for activation
The AEB gets ready to be activated, when the AEB is selected on the
LCD display, and when the followingprerequisites are satisfied.
- The ESC (Electronic StabilityControl) is activated.
- To enable the system to detect pedestrians ahead, the vehicle
driving speed must be between 8km/h – 70 km/h (5 mph – 45 mph).
- To enable the system to detect a vehicle ahead, the vehicle driving
speed must be between 8 km/h –180 km/h (5 mph – 110 mph).
When traveling above 80 km/h (50mph), the AEB system only initiates
partial braking. This is to prevent
unintended full braking to stop in the
middle of the highway.
AEB warning message and
system control
The AEB produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, or pedestrian detection. Also,
it controls the brakes in accordance
with the collision risk levels.
5
Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate
/deactivate the AEB system.
The AEB automatically acti-
vates upon placing the Engine
Start/Stop button to the ON
position. The driver can deac-
tivate the AEB by cancelingthe system setting on the LCD
display.
The AEB automatically deacti-
vates upon canceling the ESC
(Electronic Stability Control).When the ESC is canceled,
the AEB cannot be activated
on the LCD display.

Forward Warning (1stwarning)
This initial warning message appears
on the LCD display with a warning
chime.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward Collision
Warning include Early, Normal or Late
initial warning time.
Collision Warning (2ndwarning)
This warning message appears on the
LCD display with a warning chime.
Additionally, some vehicle system
intervention occurs by the enginemanagement system to help decel-
erate the vehicle.- If a vehicle is detected, your vehi-cle speed may decelerate moder-
ately.
- If your vehicle is traveling less than 70 km/h (45 mph) and a pedestri-an is detected within the Collision
Warning (2nd warning) stage, your
vehicle speed may decelerate
moderately. When your vehicle
drives faster than 70 km/h (45
mph) with a pedestrian in front, the
AEB does not operate.
Emergency braking
(3rdwarning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, some vehicle system
intervention occurs by the enginemanagement system to help decel-
erate the vehicle.
- If the detected vehicle in front isdriving slower than 80 km/h (50
mph) your vehicle speed may
decelerate sharply to avoid a col-
lision. If the detected vehicle in
front is driving faster than 80
km/h (50 mph), your vehicle
speed may decelerate moderate-
ly.

Driving your vehicle
- If your vehicle drives slower than70 km/h (45 mph) with a pedestri-
an in front, the driving speed may
abruptly decrease. When your
vehicle drives faster than 70 km/h
(45 mph) with a pedestrian in
front, the AEB does not operate.Brake operation
In an urgent situation, the braking system enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The AEB provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The AEB brake control is automat- ically canceled, when risk factors
disappear.
5
The driver should always use
extreme caution while operating
the vehicle, whether or not there
is a warning message or alarm
from the AEB system.
CAUTION
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The drivershould hold the responsibility
to safely drive and control the
vehicle.
WARNING

AEB front radar sensor
In order for the AEB system to oper-
ate properly, always make sure the
radar sensor cover is clean and free
of dirt, snow, and debris. Dirt, snow,
or foreign substances on the lens
may adversely affect the sensing
performance of the radar.
Warning message and warninglight
Auto Emergency Braking disabled.
Radar blocked
When the sensor cover is blocked
with dirt, snow, or debris, the AEB
system operation may stop tem-
porarily. If this occurs, a warningmessage will appear on the LCD dis-
play.
Remove any dirt, snow, or debris and
clean the radar sensor cover before
operating the AEB system.
The AEB may not properly operate in
an area (e.g. open terrain), where
any substances are not detected
after turning ON the engine.
Driving your vehicle
The AEB system logic operates
within certain parameters, such
as the distance from the vehicle
or pedestrian ahead, the speed
of the vehicle ahead, and the
driver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of theAEB system.

Driving your vehicle
Do not apply foreign objectssuch as a bumper sticker or a
bumper guard near the radar
sensor. Doing so may adversely
affect the sensing performance
of the radar.
Always keep the radar sensor and cover clean and free of dirtand debris.
Use only a soft cloth to wash the vehicle. Do not spray pressur-
ized water directly on the sensor
or sensor cover.
Be careful not to apply unneces- sary force on the radar sensor or
sensor cover. If the sensor is
forcibly moved out of proper
alignment, the AEB system may
not operate correctly. In this
case, a warning message may
not be displayed. Have the vehi-
cle inspected by an authorized
HYUNDAI dealer.
(Continued)(Continued)
If the front bumper becomes
damaged in the area around the
radar sensor, the AEB system
may not operate properly. We
recommend you to have the
vehicle inspected by authorized
HYUNDAI.
Use only genuine parts to repair or replace a damaged sensor or
sensor cover. Do not apply paint
to the sensor cover.
System malfunction
Check AEB system
When the AEB is not working prop-erly, the AEB warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case, we
recommend you to have the vehicle
inspected by an authorized
HYUNDAI dealer.
The AEB warning message may appear along with the illuminationof the ESC (Electronic Stability
Control) warning light.

Driving your vehicle
The AEB is only a supplemen-
tal system for the driver's con-
venience. The driver shouldhold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the AEB
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brakepedal to reduce the drivingspeed.
In certain instances and
under certain driving condi-
tions, the AEB system may
activate prematurely. This ini-
tial warning message appears
on the LCD display with a
warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The AEB system
may not activate and the
warning message will not be
displayed. (Continued)
(Continued)
If there is a malfunction with the
AEB system, the autonomous
emergency braking is not
applied even though the brak-ing system is operating normal-
ly.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The AEB system may activate during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keeploose objects secured.
The AEB system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-sion.(Continued)
(Continued)
The AEB system operates
only to detect vehicles or
pedestrians in front of the
vehicle. The AEB system does not
operate when the vehicle is in
reverse. The AEB system is not designed to detect other
objects on the road such asanimals. The AEB system does not
detect cross traffic vehicles
that are approaching. The AEB system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a deadend street.)
In these cases, you must
maintain a safe braking dis-
tance, and if necessary,depress the brake pedal toreduce the driving speed in
order to maintain a safe dis-
tance.

Limitations of the system
The Autonomous Emergency Braking (AEB) system is designed to monitor
the vehicle ahead or a pedestrian in
the roadway through radar signals
and camera recognition to warn the
driver that a collision is imminent, and
if necessary, apply emergency brak-ing.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the AEB sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
AEB operation may be limited.
Detecting vehicles
The sensor may be limited when:
The radar sensor or camera isblocked with a foreign object or
debris
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
There is interference by electro- magnetic waves
There is severe irregular reflection from the radar sensor
The radar/camera sensor recogni- tion is limited
The vehicle in front is too small to be detected by the camera recog-
nition system (for example a motor-
cycle or a bicycle, etc.)
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
The driver's field of view is not well illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view) The vehicle in front does not have
their rear lights properly turned ON
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel
The vehicle in front is driving errat- ically
The vehicle is on unpaved or uneven rough surfaces, or roads
with sudden gradient changes
The vehicle is moving under ground level or inside a building
The vehicle is driven near areas containing metal substances such
as a construction zone, railroad,etc.

5-56
- Driving on a curve
The performance of the AEB system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the AEB system may activate
prematurely.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road.
In these cases, the driver must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
The AEB system may recognize a
vehicle in the next lane when driving
on a curved road.
In this case, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
- Driving on a slope
The performance of the AEB decreas-
es while driving upward or downward
on a slope, not recognizing the vehi-
cle in front in the same lane. It may
unnecessarily produce the warning
message and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
When the AEB suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.
Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain distance.
